NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
HD3SS3411 mux channels have independent adaptive common mode tracking allowing RX and TX paths to
have different common mode voltage simplifying system implementation and avoiding inter-operational issues.
HD3SS3411 mux does not provide common mode biasing for the channel. Therefore, it is required that the
device is biased from either side for all active channels.
The HD3SS3411 supports several high-speed data protocols with a differential amplitude of < 1800 mVpp and a
common mode voltage of < 2 V, as with USB 3.1 and DisplayPort 1.3. The one select input (SEL) pin can be
controlled by an available GPIO pin within a system or from a microcontroller.
